Around my ovulation time,i had unprotected sex.this was three weeks ago and was ejaculated in.i took postinor2 exactly on the 72hours margin and was told to take both pills at the same time.my period is 9 days late.am i pregnant?

Maybe. Maybe not.: Plan B, Postinor 2, and other brands of emergency contraceptive pills can alter the menstrual cycle for the cycle in which Plan B or Postinor 2 was taken, and sometimes the next month's cycle too. One should be sure to check a home pregnancy test about 3 weeks after sex, because emergency contraceptive pills work most of the time, but not all the time.
